Comment (by wenzeslaus):

 I've executed tests with `GRASS_COMPRESS_NULLS=1` and they worked well.
 Here is what I was running:

 {{{
 export GRASS_COMPRESS_NULLS=1
 grass71 /grassdata/nc_basic/user1/ --exec python -m grass.gunittest.main
 --location nc_basic --location-type nc
 export GRASS_INT_ZLIB=0
 grass71 /grassdata/nc_basic/user1/ --exec python -m grass.gunittest.main
 ...
 }}}

 However, I think that our test coverage is quite low for this especially
 for the usage of NULLs.
